The version number is incremented to 1.0.0.
Thanks to doneir for reporting that a number of unit test were failing.
This was because two test certificates had expired. This commit replaces
these with updated certificates, along with the tool used for programmatic
certificate generation. The new certificates are set to remain valid for
approximately ten years.
A patch implementation is provided, which augments and alters the Python
standard library's ssl module to support passing of datagram sockets, in which
case this package's DTLS protocol support will be activated. The ssl module's
interface is intended to operate identically regardless of whether the DTLS
protocol or another protocol is chosen.
The following features of the ssl module are explicitly supported with
datagram sockets:
* socket wrapping, unwrapping, and re-wrapping
* threaded UDP servers
* asynchronous UDP servers (asyncore integration)
* socket servers (SocketServer integration)
The following modules have been added:
* dtls.patch: standard library module patching code and substitution
functions and methods
* unit.py: this is a port of the standard library's testing module
test_ssl.py for datagram sockets; all tests pass at this time;
a couple of inapplicable tests have been dropped; a few other
tests have been added
Also note that the err module's exception raising mechanism has been
augmented so as to raise exceptions of type ssl.SSLError (as opposed to
dtls.err.SSLError) when instructed to do so through activation of the patching
mechanism. This allows code written against the standard library module's
interface to remain unchanged. In some cases, types derived from
ssl.SSLError are raised.
This change introduces the implementation of the SSLConnection methods
getpeercert and cipher. The following has been added:
* dtls.util: utility elements shared by other modules in this package
* dtls.x509: a module for X509-certificate-related functionality,
including formatting a certificate into a Python
dictionary as prescribed by the Python standard
library's ssl module; functionality for testing with
PEM-encoded certificates in the file system is included
* yahoo-cert.pem: the current certificate of www.yahoo.com: this is a good
testing certificate, since it contains the subject
alternate name extension
Other notable changes:
* sslconnection: private attributes are now preceded by "_"
* openssl: null-ness in opaque FuncParam-derived return values is
now properly detected and an exception is raised as
expected
This initial commit for the PyDTLS package includes the following functionality:
* DTLS cookie exchange, using secure hmac cookies
* A platform-independent routing UDP demultiplexer
* SSL handshaking over UDP using the DTLS protocol
* Datagram exchange using the DTLS protocol
* SSL shutdown over UDP
The package is structured as follows:
* dtls: top-level package
* dtls.demux: demultiplexer package; automatically loads a
demultiplexer appropriate for the currently executing
platform
* dtls.demux.router: a routing demux for platforms whose network stacks
cannot assign incoming UDP packets to sockets based
on the sockets' connection information
* dtls.demux.osnet: a demux that uses the operating system's UDP packet
routing functionality
* dtls.err: package-wide error handling and error definitions
* dtls.sslconnection: a client and server-side connection class for
UDP network connections secured with the DTLS protocol
* dtls.openssl: a ctypes-based wrapper for the OpenSSL library
* dtls.test: test scripts, utilities, and unit tests
The following binaries are provided:
* libeay32.dll: cryptographic portion of the OpenSSL library
* ssleay32.dll: protocol portion of the OpenSSL library (depends on former)
* cygcrypto-1.0.0.dll: as libeay32.dll, but with debugging symbols
* cygssl-1.0.0.dll: as ssleay32.dll, but with debugging symbols
All binaries have been built with the MinGW tool chain, targeted for msvcr90.
The unstripped dll's can be debugged on Windows with gdb. Cygwin is not used.
